Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
according to an embodiment of the present invention, a connector is provided. Referring to fig. 1 to 5, the connector includes a connector housing 1 and a connection terminal 5. The connection terminal 5 is accommodated and mounted in the housing.
The connector housing 1 includes a terminal support portion 10 and a primary lock 20. The terminal support portion 10 is provided with a receiving hole 12, and the inner wall of the receiving hole 12 includes a joining region 120. The engagement area 120 is configured to be complementary to the structure of the connection terminal 5 for receiving the mounting of the connection terminal 5. In the example shown, the engagement region 120 may be provided as a flat surface.
The connection terminal 5 can be inserted into the receiving hole 12 for mating connection with a mating terminal of a mating connector. The terminal support portion 10 has a mating insertion end 102 at one side, and the mating insertion end 102 is used for inserting and connecting with a mating terminal of a mating connector. The engagement region 120 has a mating front end 122. The mating front end 122 is proximate a side of the mating insertion end 102.
The primary lock 20 is disposed on the engagement region 120 of the receiving hole 12 and is located at the mating front end 122.
When the connection terminal 5 is accommodated and mounted in the accommodation hole 12, the primary lock 20 is snap-coupled with the connection terminal 5 to prevent the connection terminal 5 from being separated from the accommodation hole 12.
In this embodiment, the primary lock 20 is directly disposed on the combination area of the accommodating hole 12, the axial lengths of the connector housing 1 and the connecting terminal 5 can be set to be shorter, the terminal material is less, and the cost is reduced.
The primary lock 20 is directly arranged on the combination area of the accommodating hole 12, the structure of the connector shell 1 is simplified, the structure of a mold for manufacturing the structure of the connector shell 1 is relatively simple, the molding period of the mold is shortened, and the mold does not need to move a sliding block.
The specific structure of the primary lock 20 may be set as required as long as the connection terminal 5 can be held in the receiving hole 12. Preferably, referring to fig. 4 to 7, the primary lock 20 includes a resilient arm 22 and a first catch 24. One end of the elastic arm 22 is fixedly connected to the joint area 120, and the other end is suspended and extends axially. The resilient arm 22 is thus configured as a cantilever structure, and the resilient arm 22 is resiliently deformable when a force is applied to the other end of the resilient arm 22. The first catch 24 is disposed on the other end of the elastic arm 22, for example, the first catch 24 may protrude from the surface of the elastic arm 22 and extend into the receiving hole 12.
More preferably, the other end of the elastic arm 22 may be extended in a direction from the outside toward the inside of the accommodation hole 12.
Referring to fig. 4 to 7, the first latch 24 may include a guide surface 240. When the connection terminal 5 is inserted into the receiving hole 12, the connection terminal 5 presses against the guide surface 240, so that the elastic arm 22 is deformed. In the example shown, the guide surface 240 may be a slope structure that is inclined axially with respect to the receiving hole 12. Furthermore, in other examples, the guide surface may also be provided in a curved configuration, for example the guide surface may be provided in a cambered configuration.
When the connection terminal 5 passes over the first catch 24, the elastic arm 22 is restored to allow the first catch 24 and the second catch 52 to be engaged with each other in the axial direction, so as to prevent the connection terminal 5 from being disengaged from the receiving hole 12, thereby holding the connection terminal 5 in the receiving hole 12.
The second snap 52 may be configured to axially engage with the first snap 24. As shown in fig. 8, a receiving groove 50 is formed on the connection terminal 5, and the second latch 52 is formed on a groove wall of the receiving groove 50. When the connection terminal 5 is accommodated in the accommodation hole 12, the first fastener 24 enters the accommodation groove 50 and is axially fastened to the side wall of the accommodation groove 50.
Referring to fig. 4, in order to prevent the elastic arm 22 from being deformed excessively, the terminal support portion 10 may include a blocking wall 14. The blocking wall 14 is located radially outside the resilient arm 22. The blocking wall may be used to define a deformation region for the resilient arm 22. For example, the blocking wall 14 and the resilient arm 22 may be spaced apart. When the connection terminal 5 is inserted into the receiving hole 12 and the elastic arm 22 is deformed, the blocking wall 14 is located at one side of the elastic arm 22 in the radial direction, and can block the elastic arm 22 from being deformed further to one side in the radial direction, so as to limit a deformation area of the elastic arm 22, and effectively prevent the elastic arm 22 from being excessively deformed or broken.
More alternatively, referring to fig. 6 and 7, the blocking wall 14 may further include a blocking step 142 extending radially inward for blocking the connection terminal 5 axially. The blocking step 142 may be provided at the mating insertion end 102 side of the terminal support part 10. When the connection terminal 5 is inserted into the receiving hole 12, the blocking step 142 forms a stopper with the connection terminal 5 so that the connection terminal 5 is fitted into the receiving hole 12.
Further, an opening 144 may be disposed on the blocking step, and the opening 144 is aligned with the elastic arm 22. The resilient arm 22 is a cantilevered structure with a free end capable of reciprocating within the opening 144.
In this embodiment, the terminal support portion and the primary lock may be provided as an integral piece. The connector housing may be a plastic part. The primary lock is of a plastic structure, can obtain better elasticity, and is easy to elastically deform when stressed. The connector may also comprise a seal 3. When the connection terminal 5 is accommodated and mounted in the accommodation hole 12, the seal 3 closes a gap between the accommodation hole 12 and the connection terminal 5. For example, the sealing member 3 may be mounted on the connection terminal 5 so as to be fitted.
In this embodiment, the connector housing 1 may be configured as a charging receptacle housing. The connector housing 1 can be plug-connected with a mating connector.
The utility model discloses in, the connector casing includes terminal supporting part and primary lock, once locks the direct setting on the combination region in holding the hole and lie in the front end to joining region's the joining region, and the axial length of connector casing and connecting terminal all can set up for a short time, and the terminal material is less, reduce cost.
The primary lock is directly arranged on the combination area of the containing hole, the connector shell structure is simplified, the mold structure for manufacturing the connector shell structure is relatively simple, the mold forming period is shortened, and the mold does not need to walk a sliding block.
The blocking wall is positioned on one radial side of the elastic arm, can block the elastic arm from continuously deforming towards one radial side, can effectively prevent the elastic arm from excessively deforming or breaking, and avoids influencing the mating connection of the connector and the mating connector.
